LOOSE-LEAF BINDER.

Application filed December 16, 1918.

To all whom it may concern:

Be it known that I, LLOYD E. Gooornan, a citizen of the United States, residing at Cedar Raids, in the county of Linn and State of lowa, have invented certain new and useful Improvements in Loose -Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to loose-leaf binders, the principal object of the invention being to provide a simple, inexpensive and convenient holder for loose leaves, from which they may be easily and quickly detached, and when attached, permitting them to be turned readily, and to lie flat in either position.

In the accompanying drawing, forming a part of this speeification Figure l is a plan view of my improved binder.

Figure 2 is an enlarged section on the line 2-2 of Figure 1.

Figure 3 is an enlarged section on the line 33 of Figure 1.

In the drawing, the numeral 10 denotes a suitable support for the leaf-holder, a tablet orbook-cover for example. The leaf-holder is a double-pronged stirrup 11 formed of a single piece of wire. The straight body portion thereof, 12 is pivotally attached to the support, so as to rock back and forth a limited distance. At each end. is an upturned arch 13 formed at right angles to the body or shaft of the holder. A simple mounting of the holder is shown in Fig. 1, being sheet metal plates 1.4 riveted to the supporting cover or tablet, and having each an eye 11.5 to receive the shaft of the leafholder. The same plate is also pierced at 1.6 to receive the free end of the arch. and one or both of such arch-ends is barbed at 17 to engage the under side of the plate when in holding position. In the case of a compara tively short and stiff holder, the barbing of one prong is suificient, but for a long and light holder, whose shaft would be more liable to twist, both prongs are barbed, as shown in Fig. 3. In this case the barbs are oppositely disposed, as shown, so that the spring of the holder shaft tends to hold them in engagement. The holes engaged by the barbed prongs should be slotted or large enough to allow for the release of the prongs,

which is effected by slightly twisting one of the arches to disengage its barb, lifting it slightly, and sliding the holder endwise in its bearings to release the other prong. When but one prong is barbed the twisting and lifting motions are all that are required, and the holes in the catch-plates 14 need be but slightly larger than the diameter of the prongs. Below these catclrplate holes are holes 18 in the tablet, and to prevent the prongs from passing through too far the holes are closed on the outer sides by sheetmetal plates 19.

It will be obvious, of course, that spring shafts 12 of different lengths may be used. interchangeably with the mounting plates 14, thus permitting standardization of the mounting plates and adapting the binders to sheets of different width, merely by spacing the mounting plates when securing the same to the binder covers according to the width of the sheets to be bound therein and using spring shafts 12 of suitable lengths according to the spacing of the mounting plates.

For leaves already perforated the prongends may be blunt, as shown in Fig. 2.

Having thus described my invention, I claim:

1. In a loose-leaf binder, a supporting tablet, a pair of catch plates attached thereto, and forming bearings for the leaf holder and a leaf-holder comprising a spring shaft having a pair of terminal arches whose free ends are oppositely barbed for engagement with the catch-plates, the arches being released by twisting one of them to spring the shaft and disengage the arch, andv sliding the shaft to disengage the other prong.

2. In a loose leaf binder, a supporting tablet, catch plates forming bearings secured to the tablet, and a leaf holder co1nprising a spring shaft mounted in the bear-- ings and provided. with a pair of terminal arches whose free ends are adapted to releasably engage the catch plates, the arches being released by twisting one of them to spring the shaft and disengage the arch and sliding the shaft to disengage the other prong.

In testimony whereof I aflix my signature in presence of two witnesses.

LLOYD E. GOODYEAR.
